Flag of Great Britain

Set down in 1606 by Royal decree of James VI and I, the flag's form combined the flag of the Kingdom of England and flag of the Kingdom of Scotland and was specifically intended for maritime use by vessels of both kingdoms, which since 1603 had shared a single monarch in a personal union following the Union of the Crowns. In 1634, Charles I proclaimed that the flag's use be restricted to vessels of the Navy Royal and Royal Scots Navy, stating that it "be reserved as an ornament proper for Our own Ships and Ships in our immediate Service and Pay, and none other".

The flag was subsequently adopted as the national flag of the unified Kingdom of Great Britain, following the Acts of Union 1707; gaining the status of "the Ensign armorial of the Kingdom of Great Britain". It was later adopted by land forces; however, the shade of blue of land-based versions appears on contemporary works of art to have been lighter than those intended for maritime use; darker dyes being used at sea for durability.

The flag of Great Britain consists of two Christian crosses; the flag consists of the red cross of Saint George, patron saint of England, superimposed on the white saltire of Saint Andrew, patron saint of Scotland. Its correct proportions are 3:5. The blue field on the flag was sky blue at first; however, over time darker shades of blue were employed to counter the effects of weathering at sea.

With few exceptions, the flag's official use came to an end in 1801, following the Acts of Union 1800 and the creation of the United Kingdom of Great Britain and Ireland whereby the Saint Patrick's Cross, representing the Kingdom of Ireland, was added to the flag of Great Britain to create the flag of the United Kingdom.

Creation

Proposed versions

In the wake of the personal union between England and Scotland resulting from the Union of the Crowns in 1603, King James instructed his Heralds to draw up designs for a new flag, juxtaposing the St George's Cross and the St Andrew's Saltire:

Early (c. 1604) design proposals for the Union Jack (manuscript in the National Library of Scotland)

However, none were acceptable to James, who in 1606 selected the design whereby the cross of Saint George was seen to surmount that of Saint Andrew.

By James VI and I, Orders in Council, 1606:

By the King: Whereas, some differences hath arisen between Our subjects of South and North Britaine travelling by Seas, about the bearing of their Flagges: For the avoiding of all contentions hereafter. We have, with the advice of our Council, ordered: That from henceforth all our Subjects of this Isle and Kingdome of Great Britaine, and all our members thereof, shall beare in their main-toppe the Red Crosse, commonly called St. George's Crosse, and the White Crosse, commonly called St. Andrew's Crosse, joyned together according to the forme made by our heralds, and sent by Us to our Admerall to be published to our Subjects: and in their fore-toppe our Subjects of South Britaine shall weare the Red Crosse onely as they were wont, and our Subjects of North Britaine in their fore-toppe the White Crosse onely as they were accustomed.

Scottish variant

In objecting to the design of Union Flag favoured by James, a number of owners and masters of merchant vessels in the Kingdom of Scotland raised the issue with John Erskine, 19th Earl of Mar, and were encouraged by him to send a letter of complaint to James VI, via the Privy Council of Scotland, which stated:

Most sacred Soverayne. A greate nomber of the maisteris and awnaris of the schippis of this your Majesteis kingdome hes verie havelie compleint to your Majesteis Counsell that the form and patrone of the flaggis of schippis, send doun heir and commandit to be ressavit and used be the subjectis of boith kingdomes, is very prejudiciall to the fredome and dignitie of this Estate and will gif occasioun of reprotche to this natioun quhairevir the said flage sal happin to be worne beyond sea becaus, as your sacred majestie may persave, the Scottis Croce, callit Sanctandrois Croce is twyse divydit, and the Inglishe Croce, callit Sanct George, haldin haill and drawne through the Scottis Croce, whiche is thairby obscurit and no takin nor merk to be seen of the Scottis Armes. This will breid some heit and miscontentment betwix your Majesteis subjectis, and it is to be ferit that some inconvenientis sall fall out betwix thame, for oure seyfairing men cannot be inducit to ressave that flag as it is set doun. They haif drawne two new drauchtis and patronis as most indifferent for boith kingdomes which they present to the Counsell, and craved our approbatioun of the same; bot we haif reserved that to you Majesteis princelie determination.

Although documents accompanying this complaint which contained drafts for alternative designs have been lost, evidence exists, at least on paper, of an unofficial Scottish variant, whereby the Scottish cross was uppermost. There is reason to think that cloth flags of this design were employed during the 17th century for unofficial use on Scottish vessels at sea.

This flag's design is also described and appears on a colour plate in the 1704 edition of The Present State of the Universe by John Beaumont, which contains as an appendix The Ensigns, Colours or Flags of the Ships at Sea: Belonging to The several Princes and States in the World.

On land, evidence confirming the use of this flag appears in the depiction of Edinburgh Castle by John Slezer, in his series of engravings entitled Theatrum Scotiae, c. 1693. Appearing in later editions of Theatrum Scotiae, the North East View of Edinburgh Castle engraving depicts the Scotch (to use the appropriate adjective of that period) version of the Union Flag flying from the Palace block of the Castle. On The North Prospect of the City of Edenburgh engraving, the flag shown is indistinct.

A manuscript compiled in 1785 by William Fox and in possession of the Flag Research Center includes a full plate showing "the scoth [sic] union" flag. This could imply that there was still some use of a Scottish variant before the addition of the cross of St Patrick to the Union Flag in 1801.

1707 Kingdom of Great Britain

Following the Union of the Crowns in 1603, King James developed the habit of referring to a "Kingdom of Great Britain" and to himself as "King of Great Britain". At his funeral in 1625, the conjoined flag was recorded as the "Banner of the Union of the two Crosses of England and Scotland". However, despite the personal union represented by James and subsequent sovereigns, in practice the Kingdom of England and Kingdom of Scotland continued as separate States, each with its own parliament, laws, currency, religion, etc. for over a century.

James' ambition to rule over a unified Kingdom of Great Britain was finally realised by his great-granddaughter Anne in 1707, with the flag of the new kingdom formally chosen on 17 April 1707, two weeks before the Acts of Union of 1707 were to take effect.

Sir Henry St George, the younger, the Garter Principal King of Arms, having presented several designs of flag to Queen Anne and her Privy Council for consideration, the flag for the soon to be unified Kingdom of Great Britain was chosen. At the suggestion of the Scots representatives, the designs for consideration included that version of Union Jack showing the Cross of Saint Andrew uppermost; identified as being the "Scotts union flagg as said to be used by the Scotts". However, the Queen and her Council approved Sir Henry's original effort, numbered "one".
